German submarine U-77 (1940)

U-77 departed Kiel on 29 May 1941. Her route took in the gap between Iceland and the Faroe Islands.

She sank the Tresillian on 13 June southeast of Cape Race ( Newfoundland ). Using her deck gun, she fired 87 rounds, scoring 60-65 hits; but it needed a torpedo to administer the coup de grâce. She then sank the Arakaka, a weather ship, on the 22nd, 450 nmi (830 km; 520 mi) east of St. Johns. There were no survivors. It was a similar story with the Anna Bulgaris south of Cape Farewell, (Greenland).

U-77 docked in St. Nazaire in occupied France on 7 July.

The boat's second foray began with her departure from St. Nazaire on 2 August 1941, but despite covering large tracts of the Atlantic, she returned to the French base on 10 September empty-handed.

For her third sortie, U-77 once more found the cupboard bare west of Ireland and the Bay of Biscay. Nothing.

U-77's next patrol was divided into two. Part one was into the Mediterranean. Leaving St. Nazaire on 10 December 1941, she slipped past the heavily defended Strait of Gibraltar and entered Messina in northeast Sicily on the 19th.

On the way, she sank SS Empire Barracuda 34 nmi (63 km; 39 mi) from Cape Trafalgar [before the Gibraltar experience], on the 15th.

Part two involved the boat's attack on the British destroyer HMS Kimberley off Tobruk on 12 January 1942. The warship's stern was blown off, but she was towed to Alexandria for temporary repairs before more permanent restoration was carried out in Bombay. The ship returned to service in January 1944.

The submarine docked at Salamis in Greece on 14 January.

Late on 1 April 1942, U-77 was attacked by a Fairey Swordfish of No. 815 Squadron FAA, north-by-northeast of Sidi Barrani. The damage inflicted meant the boat was unable to dive. She returned to Salamis on the 3rd.

Having moved to La Spezia in northwest Italy in April, U-77 departed the port for the initial portion of a two-part patrol on 6 June 1942. She sank the destroyer HMS Grove north of Sollum on the 12th. This was during Operation Vigorous, [a supply convoy to Malta].

The U-boat was unsuccessfully attacked by HMS Thrasher (N37), a British T-class submarine, off what today is the Israeli coast on 4 July. (Note: there is some confusion over this incident as the U-boat's own page on 'uboat.net' also puts her further west on that day and does not mention an attack).

U-77 finished the patrol in Salamis on 9 July.

Departing Salamis on 16 July 1942, her only victory was the Greek sailing ship Vassilliki, which she sank with 10 rounds from the deck gun east of Cyprus on the 22nd.

In late August, the boat briefly moved to Pola (or Pula) in Croatia at the 'top' of the Adriatic, from where she sortied on 12 October 1942 before steaming to La Spezia once more on 1 November.

U-77 torpedoed the sloop HMS Stork on 12 November 1942 but was attacked by the corvettes HMS Lotus and Poppy the following day northeast of Algiers. The slightly damaged U-boat returned to La Spezia on 5 December.

U-77 sank two more ships - the Empire Banner and the Empire Webster, both on 7 February 1943 west of Algiers. She had departed La Spezia on 26 January and returned there on 10 February.

In 1983, all the German soldiers and sailors buried in Spain from the WWI and WWII were exhumed from their graves and buried in this cemetery. The corpses of the U-77 were taken from the cemetery of Alicante to their final resting place in Cuacos.

The boat departed La Spezia for the last time in 3 March 1943. On 28 March, U-77 was attacked by two British Lockheed Hudsons, V of No. 48 and L of No. 233 Squadron RAF, based in Gibraltar, which dropped depth charges, and heavily damaged U-77. At 01:15 the following day, 29 March, Hartmann ordered his crew off the boat, and scuttled it in position 37°42′N 00°10′E east of Cartagena/Cape de Palos. Of the 47 crew members, nine survived the night and were picked up by Spanish fishing boats. [3]

U-77 took part in six wolfpacks, namely.

• West (6–20 June 1941)
• Grönland (10–23 August 1941)
• Kurfürst (23 August – 2 September 1941)
• Seewolf (2–7 September 1941)
• Reissewolf (21–31 October 1941)
• Störtebecker (15 November – 2 December 1941)
